Abstract

A covering for an architectural opening including a support tube and a panel operably connected to the support tube and configured to be wound around the support tube. The panel includes a support sheet and at least one vane or slat connected to the support sheet. The at least one vane includes a vane material operably connected to a first side of the support sheet and a support member operably connected to the vane material and configured to support the vane material at a distance away from the support sheet when the panel is in an extended position with respect to the support tube.

First claim

What is claimed:

1. A covering for an architectural opening comprising:
a panel comprising:
a support sheet; and
at least an upper vane and a lower vane connected to the support sheet, each of the at least upper vane and lower vane comprising:
a flexible vane material operably connected to a first side of the support sheet; and
a support member operably connected to an inner surface of the vane material and configured in a resilient arcuate shape to support the vane material at a distance away from the support sheet when the panel is in an extended position with respect to a support tube and to conform the flexible vane material to the arcuate shape of the support member when the panel is in the extended position with respect to a support tube;

wherein:
the upper vane includes an unattached bottom edge extending downwardly towards the lower vane;
the unattached bottom edge of the upper vane rests on the lower vane; and
the support member operably connected to the vane material of the upper vane contacts the lower vane when the panel is in the extended position.

2. The covering of claim 1 , wherein the support member is a thermoformable material.

3. The covering of claim 1 , further comprising a support tube, wherein the panel is operably connected to the support tube and configured to be wound around the support tube.

4. The covering of claim 3 , wherein the support member comprises an arc of curvature that is substantially the same as an arc of curvature for the support tube.

5. The covering of claim 1 , wherein the at least upper vane and lower vane are configured to extend away from the support sheet to an open position defining a chamber between the support sheet and each of the respective support members when the panel is in an extended position.

6. The covering of claim 5 , wherein the support sheet is configured to substantially collapse into the at least upper vane and lower vane, substantially decreasing a size of the respective chambers when the panel is in a retracted position.

7. The covering of claim 1 , wherein the vane material and the support member are integrally formed together.

8. The covering of claim 1 , wherein:
the upper vane includes:
a first support member; and
a first vane material operably connected to the first support member, the first vane material having a first top portion, a first middle portion, and a first bottom edge, wherein:
the first top portion is operably connected to the support sheet adjacent a first top edge of the first vane material defining a first leg;
the first top portion extends downwards adjacent the support sheet and at a first inflection point transitions away from the support sheet to the first middle portion; and
the first middle portion transitions at a second inflection point to the first bottom edge; and

the lower vane includes:
a second support member; and
a second vane material operably connected to the support member, the second vane material having a second top portion, a second middle portion, and a second bottom edge, wherein:
the second top portion is operably connected to the support sheet adjacent a second top edge of the second vane material defining a second leg;
the second top portion extends downwards adjacent the support sheet and at a third inflection point transitions away from the support sheet to the second middle portion; and
the second middle portion transitions at a fourth inflection point to the second bottom edge.

9. The covering of claim 8 , wherein:
the lower vane is positioned below the upper vane; and
in the extended position the first bottom edge is positioned adjacent to the second top portion and the second middle portion and the second top portion extends upwards on the support sheet to approximately a centerline of the first vane.

10. The covering of claim 9 , wherein:
the first support member extends along at least a portion of the first vane material between the first bottom edge and the first inflection point; and
the second support member extends along at least a portion of the second vane material between the second bottom edge and the second inflection point.

11. The covering of claim 8 , wherein the first support member and the second support member are both a thermoformable material.

12. The covering of claim 1 , wherein the support member is spaced below a top edge of the vane material.

13. The covering of claim 1 , wherein the support member is connected to the vane material approximately in line with where the vane material is connected to the support sheet.

14. The covering of claim 1 , wherein a top edge of the vane material is connected to the support sheet via a vane connection member.

15. The covering of claim 14 , wherein the vane connection member is separate from, and extends along the length of, the vane material.

16. A covering for an architectural opening comprising:
a support sheet; and
at least an upper slat and a lower slat operably connected to and extending from the support sheet, each of the at least upper slat and lower slat including:
a vane material connected to the support sheet and having a first rigidity; and
a support member having an arcuate shape and operably connected to at least a portion of the vane material and having a second rigidity, the vane material conforming to the arcuate shape of the support member;

wherein:
the support member is spaced a distance from the connection of the vane material to the support sheet, and the vane material is sufficiently stiff such that the vane material levers the support member away from the support sheet;
the first rigidity is less than the second rigidity;
the upper slat includes an unattached bottom edge extending downwardly towards the lower slat; and
the support member of the upper slat and the support member of the lower slat at least partially overlap.

17. The covering of claim 16 , further comprising a support tube, wherein:
the support sheet is operably connected to the support tube; and
the support member has a curvature that at least partially conforms to a curvature of the support tube.

18. The covering of claim 17 , wherein the at least upper slat and lower slat are operably connected to the support sheet such that a bottom edge of each of the slats faces towards the support tube.

19. The covering of claim 16 , further comprising a plurality of vanes operably connected to and extending from the support sheet on a side opposite the at least upper slat and lower slat.

20. The covering of claim 19 , wherein each of the plurality of vanes has a bottom edge that is angled in an opposite direction from a bottom edge of each of the at least upper slat and lower slat.

21. The covering of claim 19 , wherein each of the plurality of vanes includes a vane support member that is at least partially resilient and in an extended position of the covering extends the vanes away from the support sheet at least at one location.

22. The covering of claim 16 , wherein the curvature of the support member is generally “C” shaped.

23. The covering of claim 17 , wherein the support tube is rotated by a motor drive system to retract the support sheet.

24. The covering of claim 17 , wherein the support tube is rotated by a motor drive system to extend the support sheet.

25. The covering of claim 16 , wherein:
the at least upper slat and lower slat has an appearance; and
the appearance remains substantia
